Terminology
A termbase is a database containing terms, term translations, and term-related information, for example, a definition of the term. The purpose of a termbase is to reduce the amount of time and effort involved in translating new documents by enabling you to lookup term translations.
Before you start translating a document, you open a termbase and while you are translating the document, you retrieve translations from the termbase. You can use these translations to translate document segments. This is known as inserting a term translation. While translating you can add terms to the SDL MultiTerm termbase, where it will be available for selection in the future.
In SDL Trados Studio you can work with both local and server-based termbases. For more information, see Local and Remote Termbases.
